If you are having difficulty installing the PureScript compiler, feel free to ask for help! A good place is the #purescript IRC channel on Freenode, or alternatively Stack Overflow.
The prebuilt binaries are compiled with GHC 8.0.2 and therefore they should run on any operating system supported by GHC 8.0.2, such as:
- Windows Vista or later,
- OS X 10.7 or later,
- Linux ??? (we're not sure what the minimum version is).
This list is not exhaustive. If your OS is too old or not listed, or if the binaries fail to run, you may be able to install the compiler by building it from source; see below.
Other prebuilt distributions (eg, Homebrew, AUR, npm) will probably have the same requirements.
The easiest way is to use stack:
$ stack update
$ stack unpack purescript
$ cd purescript-x.y.z # (replace x.y.z with whichever version you just downloaded)
$ stack install --flag purescript:RELEASE
This will then copy the compiler and utilities into ~/.local/bin
.
If you don't have stack installed, there are install instructions here.
If you don't have GHC installed, stack will prompt you to run stack setup
which will install the correct version of GHC for you.
The PureScript REPL depends on the curses
library (via the Haskell package
terminfo
). If you are having difficulty running the compiler, it may be
because the curses
library is missing.
On Linux, you will probably need to install ncurses
manually. On Ubuntu, for
example, this can be done by running:
$ sudo apt-get install libncurses5-dev
